摘要：

We report an observation of the 6s5d 1 D 2 – 5d 2 1 D 2 forbidden transition in Ba atom by means of high-resolution atomic-beam laser spectroscopy. Stark shifts and splittings of this forbidden transition were measured for 136Ba and 138Ba using the Stark-induced interference method, increasing as the applied electric field increases. From measured spectra at various electric fields, scalar and tensor polarizabilities of the forbidden transition were obtained and found to be much larger than those of other levels. The forbidden transition with large electric polarizabilities, resulting from strong mixing between the two closely lying levels of 5d 2 1 D 2 and 5d6p 1 D 2, provides a good candidate for atomic parity non-conservation study. © 2024, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
